Welcome to Episode 4 of The Evidence Room, where every investigation uncovers the story hidden inside the evidence.Tonight we travel to rural Bavaria, Germany, to explore one of the most disturbing unsolved murder cases in European history: The Hinterkaifeck Murders.In March 1922, six members of the Gruber family were brutally murdered on an isolated farmstead surrounded by dense forest. The victims included three generations of the same family, along with a newly hired maid who had arrived only hours earlier.Before the murders, the family reported chilling events:mysterious footprints leading from the forest to the house, strange noises in the attic, and a newspaper that appeared on the property despite no one subscribing to it.When neighbors finally discovered the crime scene days later, investigators faced a baffling mystery. The killer had used a farming tool to carry out the murders, but even more disturbing was what happened afterward.Evidence suggested that the killer remained on the farm for days, feeding the animals, eating food from the house, and moving freely through the property.Despite decades of investigation and hundreds of suspects, the Hinterkaifeck murders remain unsolved more than a century later.In this episode of The Evidence Room, we examine:• The strange events reported before the massacre• The brutal attack that killed six people in one night• The disturbing behavior of the killer after the murders• The suspects and theories that investigators pursued for decades• Why the mystery of Hinterkaifeck still fascinates investigators todaySubscribe to The Evidence Room for more true crime investigations from around the world.New episodes every week.
